Hello. This post describes me much of the time. I don't usually have all bad or all good days. I go OK for a couple of hours then for no reason it becomes horrible. I work, too, so I understand how that goes. I just keep thinking that my awful mood will go away just as it came. Doesn't last forever. It's a two-edge sword because once I feel so so I start thinking about what's coming next. And that's not good. Hope it gets better for you.
